Size Genetics Extender
I bought the Size Genetics extender almost 4 months ago. Big mistake.
Their website is very slick, and they make lots of claims about how their extender is “proven” and imply that nothing else is. That is false. The product itself is a basic jes extender with a small assortment of pads/wraps, and a couple of CDs on PE and manual exercises. It costs $400, give or take.
You can buy a very similar extender on ebay for about $30 from a variety of vendors. The assortment of pads/wraps has little (if any) value. This forum offers far better advice than you will find on their CDs.
They offer a money back 6 month guarantee, in which they offer to return your money if the product does not produce any results for you. In my case, they refused to honor their guarantee. From the comments by others on this forum, I don’t think I’m the only one.
A lot of people like extenders, and find them helpful. If you want to give an extender a try, get a cheap one from Ebay first and see how it goes. You won’t be out $400 and you’ll see if it works for you. Experiment with different pads and wraps on your own, and read the extender threads on this forum. After a few months, if you decide that extenders are for you and the cheap one has serious limitations, you’ll be a more informed consumer and can make an intelligent choice about which one to buy.
